24 hour veg to sync my veg and flowering ok?

I just threw my girls into flowering but took some clones and have a couple young plants that I need to keep in veg. Im trying to get them to come on at the same time and go off at diff times but will need to leave the veg room on 24 hrs for one day. Is that ok? They are usually 18/6.

Thnx

Increase it by 1 hr. every 2 days and you will be fine.
